A magnesium alloy member having mechanical properties and corrosion resistance and a method of manufacturing the magnesium alloy member are provided. A magnesium alloy member has a base material made of a magnesium alloy, and an anticorrosive film formed on the base material. The base material is a rolled magnesium alloy including 5 to 11% by mass of Al. By using a base material including a large amount of Al, a magnesium alloy member having excellent mechanical properties and high corrosion resistance can be produced. In addition, by using a rolled material, the number of surface defects at the time of casting is small, and the frequency of compensation processes such as undercoating and puttying can be reduced.

A conductive porous body that has a conductive layer almost free from impurities and that enables a metallic porous body having extremely low resistance to be produced with high productivity and production efficiency, and a metallic porous body and a battery plate both produced by using the conductive porous body. The conductive porous body has a nickel conductive layer formed on the surface of the framework of a plastic porous body having a continuous-pore structure. The conductive layer is formed by the deposition of nickel from an aqueous solution containing nickel compounds with the use of a reducing agent containing titanium compounds. The metallic porous body can be obtained by forming a continuous metal-plated layer on the surface of the framework of the conductive porous body. The metal-plated layer is formed by electroplating with the conductive porous body serving as the cathode. The battery plate consists mainly of the metallic porous body.

To provide a molten salt battery which is highly safe and has long charge/discharge cycle life. The molten salt battery of the present invention includes a negative electrode 1 in which a negative electrode active material 12 is predominantly composed of carbon such as hard carbon. The negative electrode active material 12 is surface-treated for imparting hydrophilicity to the negative electrode active material 12 to improve the affinity for the molten salt. Further, a transition metal such as iron is added to the negative electrode active material 12 predominantly composed of hard carbon in order to enhance the affinity for the active material. The molten salt battery has higher safety in production and use and longer charge/discharge cycle life than conventional molten salt batteries using metallic sodium as an electrode.
